A double torsion spring is just as the name suggests. It is simply a spring that is designed to incorporate two torsion springs within one unit. It consists of one set of coils, wound in a right hand fashion and another set of coils, wound in a left hand fashion and are bridged through the center. The total force of a double torsion spring is the sum of the two springs added together.
Torsion springs can either have a left-hand or right-hand helix. They are made to give a force and torque when one leg is turned relative the other.
Our helical torsion springs are made in dimensions from 0.08-60 mm and we can select best solution and producing draft your torsion spring.
For closed coiled helical torsion springs there will be a friction between the coils giving a hysteresis in the torque-angle performance.
